There is a postcard of Mitcham Stadium on the Groundtastic site.

Other Info:
There appears to have been some sort of track around Mitcham Stadium which was used by Croydon Rovers football club in the 1950/51 season although the stadium existed as early as 1937 by which time it had covered grandstands down the whole of both straights and one of the straights was slightly extended. It may however have been a dog track. The infield was also used for Rugby League and in its later years for Irish Games (Hurling and Gaelic Football). The stadium was replaced by housing by the 1960s as it is not shown on an A-Z of the period and the location is now occupied by Ormerod Gardens and was on the other side of Sandy Lane to the football ground that is used by Tooting & Mitcham United FC. One of the stands was sold to Leyton Orient FC when the ground closed and the other one was also sold but need to check who to in Kerry Miller's book.
